, mechanism for mixin crude oil with a solid substance of the conslstency' of cement, sand or calcium carbide, and adding thereto a 4 liquid of the consistency of Epsom salts, or starch dissolved in water, or plain water.

The particular mechanism embodied in our invention comprises an agitating tank or container havin an oil inlet, a conveyer for positively intr ucing the solid materials for treating the oil in predetermined quantities; a valve controlled means for introducing a liquid into said tank for treating the oil; an agitating mechanism in said tank for thoroughly mixing the several substances, and means for effecting the discharge of the treated oil, said means including a centrifugal pump.

Our invention further consists in the production of simple and easily constructed mechanism as will more fully hereinafter appear. i j The accompanying drawings illustrate an embodiment of our invention as constructed for carrying out aproce'ss of treating oils in which drawings; i

. Figure 1 is a view in side elevation of our improved apparatus;

igure 21s a horizontal sectional view on the I plan, and with a portion of the conveyer casing broken away; and z 4 Figure-3 is a detail sectional view through i the valve or slide for controlliig the quantiti of solid material introduc teferring to the drawings, in which similar reference characters desi 'ate corresponding or container enerally stated, our invention involves.

net 2-2 of Figure 1, partly in top parts in the severalviews, the ap-' paratus includes among other things a tank- 1 having revolubly mounted the agitator, said shaft having a ball-bearing at its lower end, the upper end of said shaft projecting above the container and being provided with a bevel gear 4 through which gear motion is transmitted to 'the agitator in. a manner to be hereinafter described. i

The tank 1 is mounted in a supporting frame formed of uprights-5 to which are secured the transversely extending shelves orbars 6 and 7. The upper end of the container 1 is attachedby means of bolts 8 to the cross bar 6; Angle bars 9 connect the lower end of the container 'or tank with the base 10, to which latter the uprights 5 may be secured. A gauge 11 is provided on the container and the oil inlet or opening is indicated by the. numeral 12.

The means for introducing the li uid to the container 1 is supported above t e said container and includes a vertically disposed pipe or conduit'13 communicating with the top of the tank. The upper end of said pipe communicates with the lower conical or inclined .walls of the hopper 14-from which the liquid isfed. .A valve 15 is provided in said pi and controls the amount of flows of said li quid. A visual opening over which glass or other transparent material 16 is ositioned, permits the flow of the liquid to viewed.

The means for-introducing the solid ma--' terial to the container is mounted above said container and includes a screw conveyer 17 having the discharge end thereof communi-. cating with a pipe 18 projecting upwardly from the top of the container. The opposite end of the conveyer communicates with the lower end of avertically arranged pipe or conduit 19 through which the solid material fallsinto the conveyer trough surrounding the screw.. A vertical support 20 extending from the crossbar 6 may be pro- 1 vided for'the receiving end of'the conveyer and the pipe 19'. Y

Communicating with the upper end of the pipe 19 is the conical or inclined lower disloo charge end of the hopper 21 from which the solid substance or material is fed. In the lower discharge end of said hopper we provide anagitator 22 for preventing clogging of the material. This construction permits an even flow of the material from said hopper. A valve 23 is provided in the pipe 19, said valve being in the nature of .a slide having a series of various size openings 24 for regulating the quantity of material discharg'edfrom the hopper and introduced into the container. An operating lip or handle 25 may be. provided on said slide for manipintermediate or idler shaft meshes with said gear '28. The idler shaft 30 is mounted in a bearing 31 and has secured thereto 4- a gear; 32 with which latter is meshed a smaller gear or pinion 33 secured to a shaft 34. The shaft 34 is supported'in bearings 35 provided at the upper ends with brackets or standards 36 and 37. A bevel pinion is secured to one end of the shaft 34 and is designed to mesh with the larger bevel gear 4 hereinbefore referred to, thereby transmitting rotary motion to the agitating shaft '3 and in turn to the agitator. A pulley 33 is secured to the shaft 34 and is adapted to receive the belt 39 extending upwardly from a relativel small pulley 40 secured tothe power sha 41.

The power shaft 41 is journaled in suitable bearings and; has secured to its'outer .end a pulley 42 over which a belt may pass for transmittin power to the apparatus from an suitab e source, not shown.

Opera 1y connected with the power shaft- 41 is a centrifuge or centrifugal pump 43 interconnected with the discharge pipe 44 of the tank or container and designed to effect the dischargeof the treated oil and provide for its transmission through suitable pipe lines to settling vats and the like. A valve 45 is provided in the discharge pipe between thecentrifuge and container for regulating the flow of the treated oil from the container.

f Apparatus constructed in accordance with our invention will permit of the effective introduction of both liquid and solid materials for mixing with the oil in an agi tating tank, the introduction of said'treating agents being positively controlled and the amount thereof predetermined and regulated for obtaining the best results. The solid material passes from the hopper 21 and is positively fed by the conveyer 17 to the tank or container in regulated quantities, a

The 14 through the valve 15 which serves to regulate the exact quantity desired. Oil is liquid is introduced from the hopper fed to the container through the inlet opening 12. All the materials are thoroughly mixed by the agitator and subsequently withdrawn through the outlet pipe 44 and discharged through the centrifuge 43.

By our present construction it is possible to obtain the exact and desired treatment of crude oil by the use of purifying agents offluid and solid constituencies respectively.

We do not wish to be understood as limiting a hopper containing an oil purifying liquidsubstance arranged on said frame-work and provided with means for feeding regulated quantities of the purifying liquid to the container, a second hopper containing. a solid oil purifying substance, means including a conveyer for feeding said solid substance from the last mentioned hopper to said container, an agitator arranged in said container, and means including a common driving shaft for actuating said conveyer and agitator. I

2. An apparatus for treating liquid oil at atmospheric temperature including a container containing -the oi1 to be treated, a supporting frame-work for said container, means carried by said frame-work above the container for introducing an oil purifyingv liquid to said container, said last mentioned means ncludinga hopper containing an oil purifying liqui conveyer means supported by said frame-work and communicating with said container, a hopper containing a solid oil purifying agent and connected to said conveyer means, an agitator arranged in the container, and means including a common ,driving shaft for. actuating saidagitator and conveyer means.

3. An apparatus for treating emulsified oils including in combination a container having an oil inlet,-means for introducing liquid to said container for treating the oil,

a conveyer for introducing solid material tosaid container for treating the oil, means for operating said conveyer, an agitator in said COHtfllHGI, means mterconnected with said conveyer operating means for operatin said agitator, means including a cen-.' trlfuge for discharging the treated oil, and means interconnected with the aforesaid agitator operating means for operating said centrifuge. w y
